Kindly help me to solve this problem. I used Vacuum pump, specification is 630 mm of Hg (or ) 24 in Hg. and its dry vacuum pump single stage. Is sufficient to do the infusion process? Some times plate get good finishing. Some times problem will come (See the photos)

Can you provide a picture of the opposite side of the part with the flow media? It might already be enough to just heat the vacuum bag with a heat gun along the sides, so it can conform better to the edge of the fabric to avoid race tracking. cheers, Lester Thank You for valuable reply Lester.. here i attached the opposite side of the part. This side is fully impregnated. help me to solve the above problem I meant a picture of the bagged part with the flow media and vacuum line. A sketch would do if you don't have a picture...
